I believe this is a duplicate of bz581722.
The hrtimers do not get shutdown correctly. The patch hasn't made it into any kernel yet, otherwise I would just have you try it. The other bz has an attached patch. But I can whip up a scratch kernel with that patch too, if you want to verify it fixes your problem.
